Lupine SL Grano F Front Light

A compact powerhouse for road bikes and gravel bikes

Specially developed for athletic riders who don’t want to compromise on maximum performance even on the road: The SL Grano is one of the brightest, glare-free front lights in a compact all-in-one format with an integrated rechargeable battery, combining high light output, sophisticated technology, and elegant design in a robust aluminum housing.

Features of the Lupine SL Grano F Front Light

Greater range - when it counts

With its additional high beam, the SL Grano F significantly expands its range of applications beyond classic StVZO-compliant front lights. In addition to the precise, glare-free low beam, a powerful high beam with up to 1100 lumens is available, ensuring maximum visibility on dark sections.
The illumination remains as homogeneous and far-reaching as ever—obstacles, curves, and changes in the road become visible much earlier. While the low beam ensures safety on the road, the high beam offers additional range exactly when it’s needed. The result is a lighting system that performs impressively in both urban environments and on unlit roads.

Full control without taking your hands off the handlebars

The SL Grano F can be conveniently controlled using the included Bluetooth remote. Switching between daytime running mode, low beam, and high beam is done directly from the handlebars—quickly, intuitively, and safely. Thanks to modern Bluetooth Low Energy technology, operation is seamlessly integrated into the cockpit, ensuring maximum control while riding. Especially at high speeds or on challenging routes, your focus remains on the road at all times. In combination with the Rotlicht Pro BT, the system can be further expanded: the front and rear lights can be controlled together, forming a continuous, networked lighting setup for maximum safety and ease of use.

Optimally integrated into the drop - bar cockpit

Thanks to the integrated GoPro mount, the SL Grano F can be mounted under a cycling computer to save space and blends harmoniously into the cockpit of modern road bikes or gravel bikes. The sleek design, high-quality craftsmanship, and intuitive operation make this front light one of the most well-designed compact bike lights in its class. The Lupine SL Grano F StVZO is thus the ideal choice for anyone who rides for sport, values a legal, glare-free beam, and is looking for a light that perfectly combines performance, everyday practicality, and aesthetics.

Up to 1100 lumens at the touch of a button

With a brightness of up to 1100 lumens, the SL Grano F delivers an exceptionally uniform and wide beam pattern based on the proven optics of the SL Nano. The precise low beam ensures a clear cut-off line and prevents glare for oncoming traffic, while the second level of the low beam, together with the switchable high beam, provides excellent visibility even on dark country roads or fast descents. An integrated sensor detects ambient brightness and automatically switches between daytime and low beams, ensuring optimal lighting at all times.

Up to 12 hours of runtime and USB-C connection

The integrated lithium-polymer rechargeable battery, with a capacity of approximately 17 Wh and 7.4 volts, offers up to twelve hours of runtime in daytime running light mode and about one and a half hours in the brightest low-beam mode. Charging takes place via the modern USB-C connection within a few hours. The CNC-machined aluminum housing not only ensures stability and efficient heat dissipation but also meets high protection standards—with IPX6 water resistance and IK09 impact resistance, the light is ready for any weather.
